The R0 is an e-payment cash register integrated with the functions of payment, ERP system and broadcast speaker. It is targeted to the 60 million small merchants in China. It has an integrated software and hardware solution, providing a better cashier and inventory operation service. It is a breakthrough with a novel and delicate form, supporting two modes for QR code scanning payment. Customers can complete the payment either by using the hand-held device or by directly operating the device placed on the base. The design echoes ”bridge” in shape semantics: it connects merchants and consumers, and closes the gap between small business and premium service.
